Как не допустить, чтобы летние автомобили «горели»

In addition to dealing with hot and dry weather, driving in summer should also be careful of the hidden danger of spontaneous combustion of cars at high temperatures. The causes of spontaneous combustion of cars in summer are the aging of electric wires and oil circuits, resulting in leakage, inflammable and explosive materials on the car, smoking while driving, etc. The signs of spontaneous combustion of cars in summer can generally smell the smell of burnt smell. In the unfortunate event of spontaneous combustion of a car, small flames can be extinguished by themselves with a fire extinguisher while ensuring their own safety. If the fire is out of control, stay away from the spontaneous combustion vehicle as soon as possible. Car spontaneous combustion is harmful. Usually car owners should take preventive measures, pay attention to car maintenance, prevent car exposure, and prohibit flammable and explosive materials.

Causes of spontaneous combustion of cars in summer

1. The wires and oil circuits are aging, resulting in leakage. If the car engine is too oily at this time, it is particularly easy to cause spontaneous combustion.

2. Car modification is also an important reason for car spontaneous combustion, especially when it comes to the modification of car electronic circuits, such as the modification of car audio, which will bring great safety hazards.

3. Improper parking position can also cause spontaneous combustion. After parking the car, we hardly check the rear of the car. But if your exhaust pipe is just on top of various flammable materials, such as plants, paper skin, foam, etc., the consequences are unimaginable.

4. Too long high-speed driving time causes the body temperature to rise sharply, and the aging of the line causes spontaneous combustion.

5, flammable and explosive materials by direct sunlight, exposure. Sometimes things that are conveniently placed on the dashboard can easily become the fuse of self-explosion, such as lighters, power banks, perfumes, etc. Remember not to expose them to the sun.

6, the car owner smoking while driving, throwing cigarette butts, etc., is also very likely to cause spontaneous combustion of the vehicle.

Signs of spontaneous combustion of cars in summer

1. Rubber smell Generally, if there is a problem with a belt or tire, it may emit a rubber smell. In most cases, the brake or tire emits a smell.

This smell is the easiest to distinguish. When this smell occurs, first check the belt, brake shoes and tires to see if the rubber products in these parts are slack, slippery or overheated. If the smell is found to be from the brakes or tires, you should immediately Turn off the engine and stop, wait for heat dissipation before driving.

2. Plastic smell Due to the thin plastic outer sheath of the wire, overheating of the electrical circuit will lead to such situations, but most of the taste is relatively small, which is generally manifested as short circuit of the wire or local smoke and heat.

Once the wire overheating phenomenon is found, it is necessary to stop immediately to find out the reason. Although the smell of wire burning is not big, the danger index is very high. Under normal circumstances, there will be more cases of high wire temperature in summer. If it is not found in time, it is easy to cause complete circuit damage, engine cylinder pulling, and even spontaneous combustion of the whole vehicle.

The smell of unburned gasoline is likely to be an oil leak somewhere at this time, but it is generally difficult to smell, because most of the oil leaks are in the chassis position. If the car can always smell the smell of unburned gasoline, it should arouse the attention of the riders.

First of all, immediately turn off the engine, put out cigarettes and other open flames, thoroughly check the oil circuit, and determine the location and degree of oil leakage before driving on the road again. If the oil tank leaks, there is an emergency solution, which is to block the leaking part with chewed gum and send it for repair as soon as possible.

4. The smell of burning engine oil is more common in carburetor cars. People commonly call it "burning engine oil". In addition to the choking smell, the exhaust pipe will also emit black smoke.

One situation is caused by the severe wear of the inner wall of the cylinder or the severe wear of the piston, and the oil jumps into the combustion chamber of the engine. Another situation is that the valve is severely worn, and the oil may also be burned; the oil pipe of the vehicle is aging, and the oil drips on the engine or exhaust pipe, which will emit an unpleasant smell at high temperatures.

5. Strong burnt smell If you smell the special smell of non-metallic materials during driving, it is generally caused by the burning or overheating of the clutch friction plate. This kind of burnt smell will be mixed with burnt smell, because the material of the clutch plate is composed of rubber and asbestos and other materials.

If the clutch is normal to use, there is no obvious difficulty in gear or starting, and the smell of getting off the car comes from the rear of the car, then check the rear brake system for overheating. Some careless car owners forcibly drive with the handbrake, which will cause the rear brake pads to lock up and produce a burnt smell.

6. The stink of the battery. Most of this situation is electrolyte leakage or loss. This phenomenon mostly occurs on wet batteries, because this kind of battery needs electrolyte to complete the storage and conversion of electrical energy, but when the electrolyte leaks It will produce a pungent smell.

If the electrolyte is consumed too much or lost, the car generator will forcibly charge the battery, which will cause the battery to overheat and emit white smoke, and the smell will become more unpleasant. If this kind of problem is found, the electrolyte should be replenished in time and the battery should be charged.

7. Determine whether it is true or false spontaneous combustion. Sometimes when the front of the car emits white smoke or aerosol, don't panic. This is not necessarily the spontaneous combustion of the car. It may be that the front wheel brake disc malfunctions and smokes due to too intense braking. However, when you smell the smell of scorched smell and there is thick black smoke, you can be sure that the car has spontaneously ignited.

How to deal with spontaneous combustion of vehicles in summer

1. Escape the vehicle as soon as possible

When we really encounter spontaneous combustion of vehicles, we have to escape from the vehicle as soon as possible to ensure the safety of ourselves and the people in the vehicle. Under the premise of ensuring their own safety, the owner can power off the vehicle, because the power off of the vehicle can effectively prevent the combustion of the circuit and reduce the damage of spontaneous combustion.

2. Try to save yourself with fire extinguisher

There are a lot of flammable materials such as fuel, paint, plastic, fabric and leather in the car. If the vehicle really ignites spontaneously, the car can be burned into a pile of scrap metal within a few minutes. However, if we can save ourselves, it is particularly important to take effective measures to put out the spontaneous combustion when it is just a small flame. We recommend that owners keep a fire extinguisher in the car in case of emergency.

3, timely alarm and notify the insurance company.

When a vehicle spontaneously ignites, regardless of whether the fire can be finally extinguished, in a safe situation, we first call 110 to call the police; then we call the insurance company. If the spontaneous combustion insurance or related insurance is purchased, the insurance company can compensate..

How to prevent car spontaneous combustion in summer

1. The main reason for car spontaneous combustion is the aging of the oil circuit and circuit. Therefore, the most important thing to prevent car spontaneous combustion is regular maintenance, especially for cars that are more than 5 years old. First check the oil circuit to see if there is any oil leakage. If the oil leakage point is found, the pipeline must be replaced in time to prevent it.

2. After a long period of use, the power supply line on the car also has the phenomenon of aging and leakage, especially in summer sun exposure, it is easier to make the insulating tube outside the circuit aging and brittle. If the insulating tube has fine lines on the appearance, then It means that it needs to be replaced and maintained.

3. If your car's circuit has been modified by yourself, you must consider the total power consumption of the whole car, and do not use too much electrical equipment. Otherwise, if the battery is equipped with too high power, the battery will lose electricity and leak. It is easy to have electric ignition, which will cause spontaneous combustion of the car.

4. Try not to place combustibles in the car, especially plush toys, perfumes and clothing. The simpler the vehicle, the better, so as to reduce the possibility of burning the material in the car.

5. In the choice of parking lot and parking space, it is best to choose a place with shelter, such as behind the building or underground parking space, so as to protect the car from being eroded by sunlight and effectively prevent spontaneous combustion of the car.
